What you would do to get your answer is simply divide $3.60 by the # of ounces.
So this is what your problem should look like 3.60 / 24 = 0.15 or 15 cents a ounce.
A. The probability of the first box is 60% or 6/10 and the second box is 70% or 7/10

Hello!</h2>
The answer is:
Nicole has to run 6 laps when Marta has run 8 laps.
<h2>Why?</h2>
In order to calculate how many laps will Nicole have to run when Marta has run 8 laps, we need to use two equations.
We must consider that since both Marta's and Nicole's speed are constant all the time, Marta wil always run more laps than Nicole, meaning that there is not possibility for Nicole to run the same number of laps that Marta.
We know that they started at different time at the same constant speed, and when Marta has run 5 laps, Nicole has run 3 laps, there is a difference of 2 laps, and it will be always like that.
So, we can conclude that Marta will always be 2 laps ahead of Nicole.

For Marta we have:

For Nicole we have:

Now, if we want to calculate how many laps will Nicole has to run when Marta has run 8 laps, we need to use the second equation (Nicole's equation) and substitute the number of laps (Marta's lap), so, substituting and calculating we have:


Hence, we have that Nicole has to run 6 laps when Marta has run 8 laps.
Have a nice day!
Hope you can see the screenshot! And hope you understand it!
Solve for the R by simplifying both sides of the equations, then isolating the variable.
Exact form: R=787/29
Decimal Form: R=27.13793103.....
Mixed Number Form: R= 27 4/29
